Without any doubt, the Colchagua museum is a must while in Santa Cruz if you like museums, of course, it has a brief introduction on how earth started, main ages from the paleozoic era l till our days, and it gets more detail in the southern American cultures, getting more detailed towards the ones who occupied the actual Chilean land, most of then sadly extinguished by the colonization process, who is also depicted, as well as the different periods of the Chilean history to finally ends with the Colchagua valley and its huasos, in brief, is a history tell as a funnel converging in this territory. It also has an industrialization area, mainly represented by late XIX and early XX centuries, beautiful machines, definitely lovely and also liked it very much a huge collection of amber with lot of bugs and plants captured within, you have the help of augmented lens to see them through the light. Sounds good, right? It is indeed, the only missing star is because some info is not totally accurate and most because there's no written info in other language than Spanish, that's all.
